FIRELESS COOKER.

Specification of Letters Patent.

Patented April 7, 1908.

Application filed September 28, 1907. Serial No. 394,726.

To all whom it may concern:

Be it known that I, ARTHUR T. HALLOCK, citizen of the United States, residing at Grand Rapids, county of Kent, and State of f 'chigan, have invented certain new and useful Improvements "in Fireles's Cookers, of which the following is a specification, reference being had therein to the accompanfing drawing.

T s invention relates to a fireless cooker, and particularly to a structure wherein the cooking receptacle is ;packed in nonconductin material. 4

, The lnvention has for an object to provide a novel and improved construction of the case in which the cooking'rece tacle is disposed, and also of the covering or the p'ack-' .mg material therein.

A further object of the invention is to pro' vide' a novel construction of-the cover for the cookin receptacle by which the same is render-e ,nonconductive and preserved lagamst in ury from the expansion and contraction of the material thereof.

Y Other and further objects and advantages of'the invention will be hereinafter fully set forth and the'novel features thereof defined by the appended claims. a

' Referring to the drawin :'Figure 1 is a .platefor the cooking receptacle.

Like numerals refer to like .parts in the several figures of the drawing.

The numeral 10 designates the body 'of the receptacle which may be -of any desired thereto at the rear the cover .13 which is construction or configuration, and in the present instance comprises a box or casing aving the central partition '11 and provided with roller casters 12' by which it may be conveniently moved. This casing has hinged provided with fastening devices 14 adapted to cooperatewith similar devices 1:? upon the casing 10. The angles of thls casing are mortised into each other toprovide a tight joint and a series of corner blocks 16, as shown in Fig. 2, are provided at each of the angles, the upper block'of the series Within the casing providing a shoulder upon which the frame 17 rests. This frame is provided with a fabric covering 18 which protects and incloses the nonconducting material 20 forming, the packing for the receptacle 2O disposed within the casin I It hasbeen found 't at when long corner blocks are used, the wood doesnot expand endwise but transversely thus 'causin the sides and ends of the casin .to swel and break loose from the corner lock, and this difficulty is overcome by the use of a series of spaced blocks in the corners of the casing. The casing is also rovided with a series of corner irons 21 .w ch cooperate with the blocks at that point and permit the block to be used as a socket for the caster 12 inserted therein.

The pa'ckin 20 may be of any desired material, ut-it as been found thatexcelsior packing is preferable for this purpose as it does not become sour or mildewed as is the case with hay and straw, and when ressed into the casing retains its osition so t at the lining can be removed witiiout disturbing the packln By mounting the lining upon a removab e frame it can be removed for washing or renewal and readily replaced in posi-. tion thus renderin it entirely sanitary. Ex-

tending between t e partition 11 and a similar partition 22in the cover is a toggle joint 23 comprising the op osite members pivoted to each partition an to. each other. When the cover is closed these members are .adapted to seat in a recess 24 inthe partition 22 and a similar recess, 25 in the partition 11. The cover is providedwith a frame'26 similar to the frame 17 and having a fabric coverin 27 which is applied to the lidmembers an secured therein by means of the fastening devices 28 extending through the side {edge of the cover as shown in Figs. land 3 and A engage the frame therein. --;This cover is formed of a series of anels29, as shown in Figs. 2 and 3, these I eing inserted and secured in the frame 30 of the cover so as to prevent the expansion and contraction which ordinarily occurs in connection with a solid cover piece. The meetingfaces of the casing and cover have thereon a felt packing .50 to retain the heat.

The receptacles 31 disposed within the packed casing are adapted to receive any desired cooking vessel, for instance, as indicatedby dotted linesin Fig. 3, these being supported above the bottom of the receptacle by a rack 32 for that purpose, and the vessel is closed by a nonconducting cover 33. This cover is provided with the-flanged portion 34 and a central depressed body 35 which contains packing 36 of nonconducting material above which, if desired, a block 37 is inserted, While the top plate 38 thereof is provided, with the transversely extendeddovetailed groove in which a similarly depressed strip 39 is inserted with the grain thereof disposed at an angle to the grain of the cover. From this strip attaching pieces 40 extend and are bent downward over the flange 34 to retain the packed plate in osition within the receptacle cover. nder some conditions it may be desired to cook the articles within the cooking receptacle in a bag and this may be effected by attaching the bag to the periphery of this receptacle cover, as indicated-by dotted lines at 41 in ilach of the cooking receptacles is provided at opposite sides with lifting handles or bails 42 and these are adapted to receive the handles 43 which are temporarily con' nected to the eyes 44 carried by the ends of the casing. The U-shap-d ends 45 of these handles may be readily-detached from the eyes and connected'toeither of the receptacles within the casing for the purpose of lifting the same therefrom when 1t is in a heated condition. The covers for the receptacles are also provided'with the lifting eye 46,'a s

shown in Fig. 1. v

- The rack 32 supporting the cooking vessel is composed of an annular strip 47 of sheet material throughwhich the cross wires 48 extend diametrically at substantially the mid width thereof and beyond the strip 47 so,as to contact with the inner side of the receptacle within which it is disposed, while the strip 47 retains the cooking vessel in its central position upon the rack and prevents sidewise slipping thereof within the receptacle whenthe same is being conveyed to or from the chest. Under ordinary conditions the cooking is effected Within the receptacle,

'butfor some uses the cooking'vessel 31 may 50" be placed within the receptacle which may 1' contain a body of hot water and for that purpose the rack hereinbefore described is used.

In the operation of the invention the cooking vessel 1s placed within the packed receptacle and the top of thecasing closed so as to retain the heat and continue the cooking op 'eration as is usual in this class of: inventions.

Under such conditions it is important that the cover of the receptaclei'containing "the cooking vessel should be thoroughly insulated against a reduction of temperature when the lid is opened for the purpose of re movin the cooking ce tac e in the casing li ofthe receptacle is packed,

receptacleffrom the re- X 1 this purpose the as s own inthe casing.

Figs. 2 and 4;,yand in order to prevent. the warping and expansion er, the wotxien plate which holds the acking inlposition a cross strip is provided l iaving the grain running in the opposite direction to that of the disk or cover plate thus preventing any warping or s litting thereof, and this disk is secured to t 1e metal cover by means of the attaching pieces extended therefrom. This construction permits the removal and replacing of the nonconducting material within the cover.

The containing receptacle is provided with the ears adapted to receive the handles-which may also be applied to the casing as when removed no obstruction is present at the top.

of the receptacles. I

A further object of, the invention is to provide a removable linin for the packing material mounted on a ame which ma readily withdrawn from the casing an the cloth thereof washed and returned without disturbing the packing material which is particularly desirable as this lining frequently becomes soiled from cooking material spilled thereon, thus renderingthe cooker sanitary inuse and dispensin with the separate packing cushions ereto ore used at the cover of Having forth its merits, what I claim and desire to secure by Letters Patent is I 1. In a fireless' cooker, a casing rovided with a pivotally mounted cover, pac material withinsaid cover and easing, removable retaining frames inserted within they cover and casing, and a lining for the packing supported by said frames. 1
